We do not assigned this last one to the RAF whose devitrification begins around 80[degrees]C and finishes around 130[degrees]C under the same crystallization conditions [40] and is expected to occur above its vitrification temperature in aged samples [22].
Nanocrystalline soft magnetic alloys prepared by devitrification of melt-spun amorphous ribbons are interesting because of their magnetic properties superior to previously used materials, offering large inductions and good temperature stability.
The highest level dyke samples exhibit microcrystalline texture consisting of intergrown fibrolites rimming quartz and feldspar phenocrysts, reflecting greater degrees and rates of supercooling or devitrification (Stirling 1981; MacLellan and Trembath 1991), akin to aplite.

Venugopal (1979) reported that the rhyolite contains plagioclase, alkali feldspar, and embayed quartz phenocrysts set in a partially sericitized, aphanitic groundmass; a late phase of devitrification is indicated by oval patches of radiating plagioclase scattered throughout the finer groundmass.
